WHAT IS THE DIFFERENCE BETWEEN GENERATOR AND ALTERNATOR



Generator and Alternator.

Generator convert mechanical energy into electrical energy, Alternator also converts mechanical energy into electrical energy but there is the difference between both.

Generator and alternator are functionally same but the only difference in construction.  Generator persists stationary magnetic field and rotating conductor which rolls on the armature with slip rings and brushes.

Hence it converts the induced emf into dc current for external load whereas an alternator has a stationary armature and rotating magnetic field for high voltage and for low voltage it has vice versa.

All are not in details here but just names were given, for hints just. After this, you have to research it on the Internet for more details and for your knowledge on YouTube or Google. You will find more details easily when you search it by names.
Find the testing procedure names from above header pages of How Electrical blog where new beginners learn easily. Or you can direct go to Electrical switchboard testing page where you will get all these testing procedures easily by Click here and Watch this video #Siemens Switchgear.
